17 individuals arrested by Greek authorities for involvement in an $8 million cryptocurrency fraud scheme

Seventeen individuals have been apprehended by Greek law enforcement in connection with an alleged cryptocurrency investment scam, which authorities believe garnered over $8 million from a minimum of 10,000 participants.

In a statement on October 2, Hellenic Police reported that investigators in Katerini uncovered a purported pyramid scheme utilizing corporate structures and an online platform to convincingly portray cryptocurrency investments as legitimate.

Allegations of Recruitment Bonuses Among Greek Crypto Fraud Suspects

ERT News indicated that among the detained suspects, nine were military members, with two noncommissioned officers purportedly in leadership positions.

Based on information from reporter Giorgos Gerafentis, the broadcaster highlighted that members were incentivized with bonuses for recruiting new participants into the platform, creating a hierarchy where alleged leaders managed the operation while recruits helped secure further investments.

Reports from ERT suggest that initially, participants were led to believe that their investments would yield profits, but the operators subsequently failed to return their deposited funds.

The suspected offices of this network were located in Katerini, Thessaloniki, Larissa, Patras, and on an island in the Dodecanese. ERT also reported an additional nine Greek suspects connected to the case, including another armed forces member.

According to police accounts, the operation had been running since at least 2025, promoting guaranteed high returns with minimal to no risk. Investigators charged that the platform was unauthorized and promised to double investor capital within a 50-day timeframe.

Law Enforcement’s Seizure of Cash and Devices During Coordinated Raids

After an extensive investigation, law enforcement arrested two alleged leaders within the group of 17 suspects and compiled a case against nine more individuals, as documented in the official statement.

During simultaneous searches of five office spaces, nine residences, and other locations, authorities reported seizing €295,090, along with 32 mobile phones, 28 computers, and 15 tablets. The confiscated items also included 38 USBs, 16 storage drives, bank cards, and a money-counting machine.

Authorities identified 18 victims with a total of €55,970 deposited, while at least 10,000 individuals are believed to have joined the platform, according to the statement.

The detained suspects were presented before the Katerini prosecutor, who forwarded the case to an investigating judge.

Previously, Greek authorities had frozen cryptocurrency linked to an international theft incident. In July 2025, crypto.news reported on the country’s initial cryptocurrency asset seizure related to the $1.5 billion Bybit hack.

According to Chainalysis, the Hellenic Anti-Money Laundering Authority employed Reactor investigation software to link a suspicious wallet to the incident. The authority issued an emergency freezing order and escalated the case to prosecutors after following the funds’ trail.

Global Investigations Targeting Fraudulent Crypto Investment Platforms

In a report dated August 29 on 58 arrests related to crypto scams, INTERPOL detailed an eight-month operation aimed at financial networks tied to organized crime in West Africa.

Operation Jackal IV, which transpired from November 2025 to June 2026, involved 22 countries across six continents, including the United States. The investigation focused on fraudulent cryptocurrency investments, romance scams, and business email scams, in addition to the accounts and wallets handling the proceeds.

In Johannesburg, authorities arrested 39 individuals and confiscated $2.67 million while blocking 257 bank accounts, as noted by INTERPOL. The agency described suspects as having distinct roles to entice new victims into paying and urging current victims to contribute more funds.

In Romania, INTERPOL stated that the police dismantled a call center promising substantial returns from stocks and cryptocurrencies while diverting payments into wallets managed by the criminals. It was estimated that the network had stolen and laundered roughly €143 million on a global scale.

A report from July 9 outlined another international fraud enforcement initiative, dubbed Operation First Light, which resulted in 5,811 arrests and the interception of $293 million in illicit assets across 97 countries and territories.

According to INTERPOL, this operation ran from January 15 to April 30, identifying over 142,000 victims and blocking in excess of 31,000 bank accounts. Target areas included investment fraud, impersonation scams, romance deceptions, and the laundering networks supporting these crimes.

In one case from Thailand, authorities arrested two suspects associated with laundering cryptocurrency through token exchanges across various blockchains. Reports indicated that one suspect’s wallet processed transactions exceeding $122.5 million within ten months.

FBI Guidance on Frozen Withdrawals and Additional Payment Demands

The FBI’s guidance on cryptocurrency investment fraud for American investors cautions that scammers may allow early withdrawals to build trust before soliciting larger amounts.

The bureau indicates that fraudulent platforms often display enticing returns and feature professionally designed account pages, security measures for login, and customer service schemes. Victims trying to withdraw their entire balance might find their accounts frozen, facing demands for what appear to be taxes or fees.

The FBI characterizes these payment requests as yet another tactic to extract money from victims and recommends that anyone suspecting fraud cease sending funds.

Moreover, victims who have lost cryptocurrency may encounter a second wave of contact from alleged recovery services. These operators might impersonate law enforcement, private companies, or law firms, soliciting payment to recover lost assets, as per the FBI’s guidelines.

For reports submitted to the Internet Crime Complaint Center, the FBI requests transaction details, including cryptocurrency addresses, transaction amounts, asset types, dates, and transaction identifiers. The bureau also encourages victims to supply records of communications with suspects, website URLs, and details about the exchanges utilized for transfers.
